Artemis 2 moon astronauts capture space history — on their iPhones
The Artemis 2 astronauts are capturing spectacular photos of the moon and Earth on their iPhones in space.
Read MoreScientists say we’ve been wrong about what makes sprinters fast
A new international study is shaking up how we think about elite sprinting, arguing there’s no single “perfect” running style behind the world’s fastest athletes. Instead, speed emerges from a complex mix of an individual’s body, coordination, strength, and training—meaning every top sprinter moves differently. Using examples like rising Australian star Gout Gout, researchers show…
Read MoreThe world’s “oldest octopus” was never an octopus
A famous “oldest octopus” fossil has been exposed as a case of mistaken identity. Advanced imaging revealed hidden teeth showing it was actually related to a nautilus, not an octopus. The confusion came from decay that altered its shape before fossilization. This discovery rewrites part of evolutionary history, pushing the true origin of octopuses much…
Read MoreScientists just uncovered the secret behind nature’s “proton highway”
Scientists have zoomed in on how phosphoric acid moves electrical charges so efficiently in both biology and technology. By freezing a key molecular pair to extremely low temperatures, they found it forms just one stable structure—contrary to predictions. This structure relies on a specific hydrogen-bond network that may be universal in similar systems. The discovery…

“It is fascinating that an active galactic nucleus can change its brightness so dramatically over such a short period of time.”
Read More‘It just made it even more special’: Being so far from Earth makes you appreciate our planet even more, Artemis 2 astronaut says
Seeing Earth from space changes your perspective. And this “overview effect” is magnified when you’re looking back from beyond the moon, according to Artemis 2’s Christina Koch.
Read MoreThis “master gene” may be driving pancreatic cancer’s spread
A gene called KLF5 may be a key force behind the spread of pancreatic cancer—but not in the way scientists expected. Rather than mutating DNA, it rewires how genes are turned on and off, helping tumors grow and invade new areas. Researchers found it plays a major role in metastatic cells and even controls other…
Read MoreScientists discover reversible male birth control that stops sperm production
Scientists at Cornell University may be closing in on the long-sought “holy grail” of male contraception: a safe, reversible, nonhormonal method that completely halts sperm production. In a breakthrough mouse study, researchers used a compound called JQ1 to temporarily shut down meiosis—the critical process that produces sperm—without causing lasting harm. After treatment stopped, sperm production…
